General Marking Guidance

All candidates must receive the same treatment. Examiners must

mark the first candidate in exactly the same way as they mark the

last.

Mark schemes should be applied positively. Candidates must be

rewarded for what they have shown they can do rather than

penalised for omissions.

Examiners should mark according to the mark scheme not according

to their perception of where the grade boundaries may lie.

There is no ceiling on achievement. All marks on the mark scheme

should be used appropriately.

All the marks on the mark scheme are designed to be awarded.

Examiners should always award full marks if deserved, i.e. if the

answer matches the mark scheme. Examiners should also be

prepared to award zero marks if the candidate's response is not

worthy of credit according to the mark scheme.

Where some judgement is required, mark schemes will provide the

principles by which marks will be awarded and exemplification may

be limited.

When examiners are in doubt regarding the application of the mark

scheme to a candidate's response, the team leader must be

consulted.

Crossed out work should be marked UNLESS the candidate has

replaced it with an alternative response.

PEARSON EDEXCEL GCE MATHEMATICS

General Instructions for Marking

1. The total number of marks for the paper is 75

2. The Edexcel Mathematics mark schemes use the following types of marks:

M marks: Method marks are awarded for `knowing a method and attempting to apply it', unless otherwise indicated.

A marks: Accuracy marks can only be awarded if the relevant method (M) marks have been earned.

B marks are unconditional accuracy marks (independent of M marks) Marks should not be subdivided.

3. Abbreviations

These are some of the traditional marking abbreviations that will appear in the mark schemes.

bod ? benefit of doubt

ft ? follow through

the symbol will be used for correct ft

cao ? correct answer only

cso - correct solution only. There must be no errors in this part of the question to obtain this mark

isw ? ignore subsequent working

awrt ? answers which round to

SC: special case

oe ? or equivalent (and appropriate)

d... or dep ? dependent

indep ? independent

dp decimal places

sf significant figures

The answer is printed on the paper or ag- answer given

or d... The second mark is dependent on gaining the first mark

4. All A marks are `correct answer only' (cao.), unless shown, for example, as A1 ft to indicate that previous wrong working is to be followed through. After a misread however, the subsequent A marks affected are treated as A ft.

5. For misreading which does not alter the character of a question or materially simplify it, deduct two from any A or B marks gained, in that part of the question affected.

6. If a candidate makes more than one attempt at any question: If all but one attempt is crossed out, mark the attempt which is NOT crossed out. If either all attempts are crossed out or none are crossed out, mark all the attempts and score the highest single attempt.

7. Ignore wrong working or incorrect statements following a correct answer.
